Sometimes you need to the dates for holidays in PHP. All of the following will return timestamps.

function victoria_day() {
	$t = strtotime('May 25');
	return $t - (date("N")-1)*24*60*60;
}

Finding (Canadian) Thanksgiving in PHP

$thanksgiving = strtotime('second monday of November');

$thanksgiving = strtotime('First monday of September');
